We love great software, and sometimes paid software has its place—but great free software will always hold the most special place in our hearts. We want to know: what free apps are you most thankful for this year?

As usual, we'll be rounding up our favorite free apps this Thanksgiving to show appreciation to the developers and communities that make them happen. Here's your chance to nominate your favorites: let us know which ones you love in the discussions below, and check back on Thanksgiving Day for the list of the best.
